I like going on ghost hunts and this game (before Dark Moon) really hit the spot. I had to use the two Flashy Infijumpers (that I found) on the stack of Boos and Big Boo to defeat them instantly. The funny part of this level is the 5 Boos having a Disco Party on the second floor's right door. The Steward's panting also creeped me out when I saw a Boo's face replacing the portrait's face. Outside, a Boo was going to scare the Steward from behind, until I put out the fire with the hammer. Also, the Secret Door just sends me back to Decalburg's west. This is one of the best levels I've seen in this game, and I agree with SZ; Instead of the Ski Lifts, Luigi should have been inside the mansion.
